Definitions

  • the n-channel MOS type transistors in the imaging region and the n-channel MOS type transistors in the drive circuit region usually have the same structure.
  • the stated manufacturing method can manufacture a solid-state imaging apparatus with high quality images and less noise during the driving operation that is capable of reducing the damage on the photodiode unit and the amplification unit, which is a cause of the leakage current in the photodiode unit and the characteristic deterioration in the amplification unit.
  • the MOS type transistors formed in the both steps are of n-channel MOS type.
  • circuits included in the regions 10 and 20 are shown as blocks. In practice, however, functional device units included in the regions 10 and 20 are densely formed on the Si substrate 31.
  • each of the pixels 11 to 16 accumulates the signal charge generated by the photoelectric conversion.
  • the signal charge is amplified and output.
  • circuits 21 to 24 included in the drive circuit region 20 the following describes the circuit structure of the horizontal shift resistor 23, with reference to FIG.3.
  • the drain region of the output transistor 2322 included in the 2 nd stage 232 is connected with a signal line for a drive pulse V2.
  • MOS type imaging apparatus 1 pertaining to the embodiment of the present invention is characterized in that all the transistors included in both the imaging region 10 and the drive circuit region 20 are n-channel MOS type transistors. The following describes the device structure of the transistors with reference to FIG.5.
  • the four steps for removing resists namely steps 3, 6, 11 and 14 damages the surface of the Si substrate 61 on which the photodiode unit is to be formed, and this damage becomes the cause of the leakage current during the driving operation.
  • This leakage current is to be added to the signal generated by the photoelectric conversion, resulting in the deterioration of the image quality caused by an increase of pixel defects.
  • the manufacturing method pertaining to the embodiment suppresses the 1/f noise in the amplification unit caused by a defect at a bottom part of the gate electrode 35, a leakage current in the amplification unit caused by damage of the gate insulator 32 on both sides of the gate electrode 35, and a leakage current in the photodiode unit caused by a defect of the Si substrate 31 at a bottom part of the photodiode unit.
  • the leakage current can be greatly suppressed when the gate insulator 32 is a thin film of which the thickness is not more than 20 (nm) as well. This shows that the MOS type imaging apparatus 1, in which all the transistors are formed with n-channel MOS type transistors, has advantages.
